Machine for cutting out boot and shoe soles



ATENE JESSE W. HATCH, OF ROCHESTER, NEW YORK.

MACHINE' FOR CUTTING OUT BOOT AND SHOE SOLES.

To all 'whom it may concern:

Be it known that I, Jrssn IV. HATCH, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Machines for Cutting Out Leather, Cloth, India-Rubber, and other Substances; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- F ig'ure l, is a back view of a machine constructed according to my invention for cutting out soles for shoes or boots. Fig. Q, is atop view of the same. Fig. 3, is a vertical section of the cutter and its appendages. Fig. t, is a detached sectional view which will be hereinafter explained.

Similar letters of reference indicate corresponding parts in the several igures.

This invention consists in certain improvements in the patented machine of J. W'. Hatch and H. Churchill, and the principal object of t-hese improvements is to enable the machine to be driven and operated entirely by one person, and thus to remedy the inconvenience of Hatch and Churchills machine which where power is not used requires one person to drive it and another to supply it with material and remove the cut articles.

To enable those skilled in the art to make and use my invention I will proceed to describe its construction and operation.

In this machine the cutter, A, which is of the character of what is known as a gun punch, is attached to a vertical shaft or stock, B, which is provided with journals to work in suitable bearings in a slide, P, working in vertical guides in the framing, C, of the machine; and it receives the vertical rectilinear motion necessary to produce its cutting action from an eccentric pin a, see Figs. l, and 3, on a horizontal shaft, D, acting on the slide, P. It derives the semirotary motion which is given for the purpose of reversing its posit-ion after every cut for the prevention of waste, from a horizontal lever,`E, on the topof the machine which has a toothed sector o, at its front end gearing with a pinion or sector, g, on the top part of the shaft or stock. In all these respects it resembles the machine of Hatch and Churchills, but instead of a continuous rotary movement derived from a crank or pulley at the back as in that machine, the shaft in this machine makes only about three fourths of a revolution in opposite directions alternately, the said movement being produced by a treadle, F, which is a lever of the first order with its fulcrum, g, at the rear end secured to the floor or to a suitable bed plate, said treadle being connected by a rod 0, with a wrist, b, at the back of the fly wheel, G, of the shaft, D. The extent of this movement is indicated by the wrist, b, being represented in two positions in Fig. l. lfVhile the machine is at rest, the wrist is always held in one of these two positions by a weight, o, attached to or cast on the fly wheel the said weight resting upon one of two fixed standards f, f. In either of these conditions of the wheel and wrist the treadle is of course raised. The operator stands in front of the machine in a convenient position for placing the pieces of leather or other material in a proper manner upon the table, H, for the action of the cutter and `when he depresses the treadle by his foot he moves the wheel far enough to bring the weight r, over the center of the shaft, D, but the momentum the weight has acquired in moving to that point carries it past t-he center and there the pressure of the foot being taken from the treadle it descends by the force of gravity until it reaches the other standard thus completing the movement of the wheel. This movement of the wheel brings down the cutter and raises it again and just before its termination itl moves the lever E, to reverse the position of the cutter by the action of one of two projections CZ, d, upon one of the prongs e, e, of a fork on the rear end of the lever. The prongs e, e, of the fork are at different elevations and the projections (Z, cZ, at different distances from the shaft, D, to correspond with the elevation of the prongs e, e, so that when the wheel moves in the direction of the black arrow shown in Fig. l, the projection el, may pass under the higher prong e, and strike the lower prong, e, thus throwing the lever to the position shown in Fig. 2, but that when the wheel moves in the direction of the red arrow the projection, d, may pass over the lower prong, e, and strike the higher prong, e, thus throwing the lever to the position t-he reverse of that shown in 2. The movement-s thus given to the lever take place just before the weight comes in contact with the standards f, f',

forced up against the 4lever to produce thev necessary friction by tWo india rubber springs z', z', one at each end. Stop screws j, j, are also applied to the yoke I, to stop and regulate the movement of the lever.

The spring discharging plate, j, in the center of the cutter is applied in this 1nachine somewhat differently to Hatch and Churchills, being attached to a rod lo, passing entirely through the cutter shaft and having a spring l, applied at the top of the shaft as shown in Fig. 3.

What I claim as my invention and desire t0 secure by Letters Patent is" 1. The projections cl, cZ, at' different distances on the face of the Wheel, and the fork e, e, on the sector lever E., having its prongs at different elevations combined and operating substantially as herein set forth.

2. The application of the spring friction bar h, to the yoke I, for preventing the return of the sector lever before the proper time, in the manner specified.
